report_mig_mult-class: Migration reports for multiple DC / species / stages

In stacomiR: Fish Migration Monitoring

Migration reports for multiple DC / species / stages

Description

Migration counts for several Fish counting devices (DC), several taxa and several stages. This migration count can be built either by the graphical interface or from the command line (see examples).

Slots

dc

An object of class ref_dc-class

taxa

An object of class ref_taxa-class

stage

An object of class ref_stage-class

timestep

An object of class ref_timestep_daily-class

data

A data.frame containing raw data filled by the connect method

calcdata

A 'list' of calculated daily data, one per dc, filled in by the calcule method

coef_conversion

A data frame of daily weight to number conversion coefficients, filled in by the connect method if any weight are found in the data slot.

time.sequence

A POSIXt time sequence

Note

A Migration report comes from a migration monitoring : the fishes are monitored in a section of river, this section is called a control station (station). Most often, there is a dam, one or several fishways (DF) which comprise one or several counting devices (DC). On each counting device, the migration is recorded. It can be either an instant recording (video control) or the use of traps, Operations are monitoring operations during a period. For each operation, several species of fishes can be recorded (samples). In the case of migratory fishes the stage of development is important as it may indicate generic migrations, to and fro, between the river and the sea.

Hence a Multiple Migration report is built from several one or several counting devices (DC), one or several Taxa (Taxon), one or several stages (stage). The migration can be also recorded not as numbers, but in the case of glass eels, as weight, which will be later transformed to number, from daily conversion coefficients. The methods in this class test whether the counts are numbers or another type of quantity. This class makes different calculations than report_mig, it does not handle escapement coefficients, it uses quantities other than numbers if necessary (only used for glass eel in the connect method).
